The keyless entry control module,
The KECM wiring
A dealer with a Tech 2 programmer to reprogram your PCM and BCM with the KE configuration.
It'* more trouble than it is worth. But what intriques me is, I thought all GM vehicles came stock with KE after 2002?
Try this test,
Get in car, close all doors
Hold down the door LOCK button
Cycle key to ON(Not start) and back to OFF 3 times.
Let go of the power lock button. If doors lock and unlock by themselves, then you have KE but no remotes. That'* the programming procedure for remotes.
